KVM is an open source originated from the x86 server world. The Linux kernel effectively becomes the hypervisor with the
KVM kernel module.
Big strength of KVM is the large open source community-- we can leverage a significant amount of effort that has gone into
this technology.
Our intent is to push KVM technology in a direction that makes is useful for embedded systems--- running OSes besides
Linux, allowing partitioning of SoC hardware resources.

Two general approaches to I/O
− Virtual
I/O devices

Software emulation of real hardware device-- register-level
emulation

Virtio
− Direct
assigned I/O devices
Virtual I/O is how you allow multiple domains/guest/virtual-machine share a hardware I/O devices.
Advantage of emulation of real hardware device is that guest drivers do not have to change. The
virtual machine makes it look identical to the real hardware that is being emulated. Disadvantage is
slow performance.
Virtio is a technology in Linux and Qemu that allows sharing of network, block (e.g. disk), and console
devices-- designed for virtualization and has improved performance.
Direct assigned I/O devices is something new that Freescale has developed due to the needs of
embedded systems– allows a guest OS private ownership of devices and direct access to device
registers.

Overview
− Freescale


Book E CPUs have 2 hardware TLBs–
TLB1 allows variable sized pages with locking
TLB0 has 4KB pages, is set associative, and entries are typically
recycled
− Guest
TLB operations (e.g. write, invalidate) must be validated by
the hypervisor.
•
The pressure (or lack of) on TLB0 will be a significant factor in
overall hypervisor overhead. Every TLB miss implies the need to
write a new TLB entry (which must be validated)
►Processor
Roadmap: logical to real address translation (LRAT) in
CPU expected to eliminate hypervisor overhead in TLB
managment

LRAT is defined in Power ISA 2.0.6
On a TLB write, a hardware table translates the guest physical
address to true physical. tlbwe does not trap to HV.
If the guest physical address misses in the LRAT the hypervisor
services and decides whether mapping is allowed.
Only valid mappings are placed in the LRAT. These are
typically large mappings so the vast majority of TLB writes can
complete without a trap.
An LRAT should solve the overhead associated with TLB misses
to TLB0
With LRAT a new hardware lookup table handles guest
physical address translation instead of it being done in
software by the hypervisor

USDPAA is a change in deployment context for “data plane” run-tocompletion software. USDPAA = LWE in Linux user space.

• USDPAA – deployed in a Linux user space process

Benefits:
• Richer, more flexible environment– use Linux standard services
rather than inventing new ones (C++, 36-bit, 8th core, debug, etc).
• More standard– Linux is ubiquitous and supported from multiple
sources.
• Provides high-performance run-to-completion but other use-cases
also– a use case super-set.

Some portals can be allocated to the Linux kernel. Others are free to
be dedicated to an USDPAA thread (that is in turn affine to a core).
USDPAA Thread Affine to Core
Kernel Drivers
USDPAA threads directly map and access the
portal that is dedicated to them.
Portals allocated to the kernel are accessed via inkernel drivers. These provide enqueue/dequeue and
other services to a next layer of kernel drivers such as
standard ethernet drivers that use QMan to exchange
frames with FMan. One portal multiplexes several
kernel drivers.

• “Work” (like packet) is enqueued into QMan by a worker (e.g. FMan)
• QMan scheduler acts as a HW “work” scheduler
• Different types of work are assigned to specific frame queues.
• Frame queues are placed into work queues for scheduling.
• QMan enforces atomicity (no locks) when needed
• Qman schedules the work to another worker (e.g. a core).
• Repeat (in possibly many steps) until processing is done.

Rationale: It is not practical for kernel based software to track
relationships between resourced that are shared between
applications or applications and the kernel.
•
It is not practical for kernel software to dictate policy in these
cases.

API Objects
•
Each “object” in the API is represented by a data structure which holds
the members of the „class‟
•
The methods of a class are API routines which take as first argument
the object‟s handle, i.e. a pointer to the object‟s data structure
•
Initialization Routines
•
The object configuration routine functions as a constructor It returns a
handle to the newly created instantiation of the object. The init routine
applies the configuration to the hardware.
•
The object free routine functions as a destructor of the SW object, but
also clears the HW initialization.

During initialization of each module that uses irqs,
the application specifies its irq number.
It is responsibility of the application above the driver
to manage the number of the irqs in the system
The driver registers to its irqs using the system
supplied XX routines:
− XX_SetIntr / XX_FreeIntr
− XX_EnableIntr / XX_DisableIntr
If application don‟t want the driver to register to
interrupt, it should pass „NO_IRQ‟ as a parameter to
the driver during initialization
